TO ALL WHOM IT MAY CONCERN:

Be 'it known that I, CHARLES A. MAXFIELD, of the city and State of New York, have invented, made, and applied to use a certain new and useful Improvement in Machine for Folding Boxesand Box-Envelopes; and I do hereby declare the following to be a full, clear, and exact description of the said invention, reference being had to the annexed drawing, making part of this specification, wherein- Figure 1 is a vertical section of'the said machine through the'folding-die.

Figure 2 isa sectional plan, showingthe bed, with the sheet of paper to -form the box shown in red lines, and the plunger or former in blue lines.

Figures 3, 4, and 5 are perspective viewsof the folded box in its various'stages.

Similar marks of reference denote the same parts. p

The object of my invention is to fold up into the shape of a-box, a sheet of paper or other material, previously cut out to shape, and to effect this operation,,with great rapidity and precision, so that box-envelopes, paper boxes, and, a variety of box-shaped bags, of any-desired size and character, can be folded with but little cost. I I I Y My invention consists in a series of folders,combined with a former in such a manner that the sheet of material is folded against and wrapped around said former, the'parts acting successively as the plunger is forced into-a die containing thes folders, and carries the paper or other material with it, delivering the same in the form of a folded box or box-envelope.

In the drawing, a is a bad, with standards, '6 b, in which is titted to slide the head-block, with its plunger,

0, the sides of which are parallel or nearly so, and of a size corresponding to the interior of the box to be formed;

This plunger hence becomes a former, and it is actuated by a lever, d, or other convenient means.

The bed a has anopening through it, and the edges 2 2 thereof form the first fold of the paper or other material as the plunger is brought down upon it,-carrying the samein between the edges 2 2. I

V In fig. 2, the red lines show the shape of the box-material as cut out to shape, and laid down-toits position within the gauge or fence, 0.

f andgform the sides of'the box, 7t h the first folded portionof the sides,2'2'the second portion ofth sides, that extends from the bottom, k, of. the box, and H the portion of the sides last foldd. The interiorsurfacesof the portions 1' z' and It should be covered with glue, or other adhesive material, so as to unite with the surfaces into which they are turned into contact. I

In the manufacture of box-envelopes, the folding-flap, m, and corner-pieces,n, are also provided. They are to be creased and folded at the dotted lines, shown in figs. 3, 4, and 5, so as to complete the cover or flap ofthe,

box-envelope. This feature, however, forms no partof my presentinvention, as the box may be formed of. any desired shape, either with or without the cover or flap. V d

As the plunger'descends, and the edges 22 fold up the sidesfg, the further descent of the forri1er,c, brings the material in contact with-a stationary folding-stud, 3, that folds in the side-pieces It towards and'upon the former, 0, then the parts t'e'are turned up, as seen in fig. 4, against the side-pieces h, by coming in contact with the second sctof folders 4 4 and so or the last fold of. the side-pieces Zlis made by the folders 5 5.

The edges of these folders 3, 4, and 5 are to be rounded, so as not to out the paper or other material, and they maybe adjustable, so as to suit different thicknesses of material or sizes of box. 4

The gauge or,fencc e may be shaped so as to'receive the flap of the box-envelope, shown in fig. 2 by red lines.

The box is carried through the die formed ofsaid folders, and taken by a. suitable device, and the former, c, draws up out ofit. v i

What I claim, and desire to secure by Letters Patent, is-

The former, c, in combination with the folders 2 3 4 5, substantially as specified, so that the folding of a box or box-envelope is eil'eeted by driving the previously-cut sheet of material through between said folders, as set forth.

In witness whereof, I have hereilnto set iny signature, .this 29th day of July, A. D 1867. v k
